Carving tools and other short tools such as small butt chisels are never the easiest to 'jig up'. This relatively simple jig answers the problem very well, the tool is clamped firmly and then its a simple matter of adjusting the tool rest in height to achieve the chosen grinding angle. The internal vee shape automatically centres the tool and allows for quite narrow tools and power carving blades to be sharpened on the Jet Wetstone. This is a real must have accessory.
